How we measured this
Confidence in this measurement: medium.
- Realtime quality was not measured this run. It does not count against the grade.
- The feed was downloaded from the official feed URL on file.
Confidence describes how much the pipeline could measure this run, not the feed itself. It never changes the grade.

Review the rule documentation for 'decreasing_shape_distance' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.
Decreasing shape distance (flagged by the MobilityData validator). See the linked rule for what this affects.
This is a validator notice, and the validator decides what each instance covers, so no share of the network can be read from it here.

Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops.Likely your team
92 of 92 stops don't say whether a wheelchair user can board there. Riders who use wheelchairs can't plan a trip when accessibility is marked 'unknown'; apps show no information at all.
Fixing this covers all 92 stops in the feed.

Riders and need behind these fixes
- Rider-trip figures come from the United States National Transit Database, which does not cover this feed's country.
- The served-area need overlays cover the United States and Canada, so none of them applies to this feed.
These describe this feed only. They do not rank agencies, and they do not change the grade or the order of the fixes.

Rider view: what this feed publishes
A quick read of rider-facing information in this feed.
- Schedule visibility
- The feed's last published service date is in 228 days.
- Published accessibility data
- Accessibility information is stated for 0% of stops and 0% of trips. This measures published data, not whether stops or vehicles are physically usable.
- Fare information
- Fare information is published using GTFS Fares v1.
- Realtime information
- Realtime-feed availability and live-arrival coverage are not known from this scorecard.
Important: This does not rate service reliability. Riders should confirm current service alerts, fares, and accessibility accommodations with the transit operator before traveling.

You may not control the GTFS export yourself. Copy this and send it to whoever runs your scheduling software export. It names each fix with the validator notice and a guide link.
Score by category
The MobilityData validator flagged 6 kinds of issue across 155 instances (108 error, 46 warning, 1 informational).
Service data covers the next 228 days.
0% of stops state wheelchair accessibility (0% marked accessible, 0% marked not accessible). This measures what the feed publishes, not whether a stop is physically usable. Fare data is published.
0% of stops state accessibility (0% marked accessible). Reflects what the feed states, not verified physical usability.
3 accessibility depth signals
4 route badge(s) pair a color and text color below the WCAG 4.5:1 contrast bar (VOIR, GRES, SUD, VERC).
Consider: Adjust route_color or route_text_color so each pair clears 4.5:1. Often switching the text between black and white is enough.
8 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("Crolles, Crolles - Av. Ambroise Croizat", "Tullins, Tullins - Av. de la Gare", "La Pierre, La Pierre - Carr. RD 523", and more).
Consider: Add tts_stop_name with the spoken form, e.g. 'Main Street and Second Avenue', for the affected stops.
This feed models stations or entrances but has no pathways.txt and levels.txt.
Consider: Add pathways.txt connecting entrances, platforms, and elevators, and levels.txt for each floor, so the step-free route is described.
Opportunities to strengthen the data, not deductions from the sub-score above. States what the second accessibility lens can check from the feed, not verified physical usability.
Fares are applied to trips.

- Error108 instances
Decreasing shape distance (flagged by the MobilityData validator).
See the linked rule for what this affects.
Fix: Review the rule documentation for 'decreasing_shape_distance' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)
Finding code: decreasing_shape_distance · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning276 instances
276 of 276 trips don't say whether the vehicle is wheelchair accessible.
Even with accessible stops, riders need to know the bus itself can take them.
Fix: Set wheelchair_accessible on every trip. If every vehicle is accessible, this may be one default; otherwise use the value for each trip. (A default or per-trip field in your export.)
Finding code: scorecard_wheelchair_accessible_unknown · Read the fix guide for scorecard_wheelchair_accessible_unknown · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)
- Warning92 instances
92 of 92 stops don't say whether a wheelchair user can board there.
Riders who use wheelchairs can't plan a trip when accessibility is marked 'unknown'; apps show no information at all.
Fix: Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops. (A column in stops.txt; your scheduling software likely has it.)

- Warning31 instances
Some route lines list the same point twice in a row.
Repeated points don't hurt riders, but they can skew distance math and hint at a shaky export.
Fix: Turn on shape cleanup in your export tool, or drop the repeated points from shapes.txt. (Usually one export setting.)
Finding code: equal_shape_distance_same_coordinates · Read the fix guide for equal_shape_distance_same_coordinates · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning10 instances
Some stops sit far from the route line they belong to.
Trip planners may draw the bus route through the wrong streets or point riders to the wrong corner.
Fix: Check the flagged stops' coordinates and the route shape in your scheduling software; re-snap whichever is misplaced. (A few minutes per flagged stop.)
Finding code: stop_too_far_from_shape · Read the fix guide for stop_too_far_from_shape · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning4 instances
Some files leave out fields that GTFS asks for but does not require.
Recommended fields like agency_phone or stop descriptions make the feed more useful to riders and trip planners.
Fix: Review the flagged fields and fill in the ones your riders would use. (A field at a time; not urgent.)
Finding code: missing_recommended_field · Read the fix guide for missing_recommended_field · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning1 instance
feed_info.txt lists no contact email and no contact URL.
Without a contact, apps like Google Maps can't reach you when they find a problem in the feed.
Fix: Add feed_contact_email or feed_contact_url to feed_info.txt. (One field, set once in export settings.)
Finding code: missing_feed_contact_email_and_url · Read the fix guide for missing_feed_contact_email_and_url · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning1 instance
feed_info.txt is missing its start/end dates
Apps and this scorecard can't warn anyone before the feed goes stale without stated validity dates.
Fix: Add feed_info.txt with feed_start_date and feed_end_date to your export. (Two fields, set once in export settings.)
Finding code: scorecard_missing_feed_info_dates · Read the fix guide for scorecard_missing_feed_info_dates · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning1 instance
This feed offers flexible service that riders book ahead, but it has no booking_rules.txt.
Riders can see the service area but not how or when to book a trip. Without that, they can't use the service.
Fix: Add booking_rules.txt saying how far ahead and how to book (phone, app, or web). (A small file; one rule often covers the whole service.)
Finding code: scorecard_flex_no_booking_rules · Read the fix guide for scorecard_flex_no_booking_rules · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)
- Warning1 instance
This feed models stations or entrances but has no pathways.txt.
Trip planners can't guide riders through the station, and there is no step-free route information for wheelchair users.
Fix: Add pathways.txt to link entrances, platforms, and elevators. Give each one a level. (Worth it for multi-level or large stations; flat stops don't need it.)
Finding code: scorecard_station_no_pathways · Read the fix guide for scorecard_station_no_pathways · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)
- Info1 instance
Some files contain columns that are not part of the GTFS spec.
Harmless to riders, but apps ignore these columns and they can hide typos in real column names.
Fix: Check the flagged column names for misspellings of standard GTFS fields; remove them if they are vendor extras. (A quick look at the flagged files.)
Finding code: unknown_column · Read the fix guide for unknown_column · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Info1 instance
feed_info.txt has no technical contact (feed_contact_email or feed_contact_url).
App makers and state data programs have nobody to email when they spot a problem. Small errors then sit in the feed for months.
Fix: Add feed_contact_email to feed_info.txt. (One field.)

Beyond the grade
Opportunities that do not change your grade today: fare detail, on-demand service, and deeper accessibility data.
Flex zones are published but no booking_rules.txt is present.
Consider: Add booking_rules.txt with how far ahead and how to reserve (phone, app, or web).
Conformance mark Not yet
Two requirements remain for this feed to earn the conformance mark. 1 validator error to resolve. States wheelchair access on 0% of stops and 0% of trips; the mark needs 90% of each.
- Valid Not yet
- 1 validator error to resolve.
- Current Met
- Service data covers the next 228 days.
- Accessible Not yet
- States wheelchair access on 0% of stops and 0% of trips; the mark needs 90% of each.
In plain words: earn this mark when your feed passes validation, has not expired, and says whether nearly every stop and trip is wheelchair accessible.
A pass credential for a feed that is valid, current, and states wheelchair access on nearly every stop and trip. Accessibility here measures what the feed publishes, not whether a stop is physically usable. How the conformance mark works.
Clears the Google and Apple Maps four-week coverage bar. This feed has 227 days of service ahead, clearing the four-week (28-day) window Maps asks for. The feed also carries 108 validator errors, the other thing Maps checks at onboarding; the findings below name each fix.
How this agency maps to the standards
The scorecard is a data-quality lens, not a compliance determination. Its universal references describe good GTFS and useful rider information. Useful references here are GTFS Schedule Best Practices, GTFS-Realtime Best Practices, MobilityData grading scheme, Google Transit publication guidance. Read the full standards crosswalk.
- Correctness 56 / 100
- GTFS Schedule best practices, checked by the MobilityData validator. MobilityData grading covers stop locations, route names, and colors. Google Transit requires a feed to pass validation for publication.
- Freshness 85 / 100
- GTFS Schedule best practices call for a dataset that stays current. An expired calendar can remove service from Google Transit and other rider trip planners.
- Rider experience 52 / 100
- GTFS Best Practices for rider-facing fields. MobilityData grading covers stop names and headsigns.
- Realtime quality Not yet published
- GTFS-Realtime best practices: a stable URL, high uptime, and frequent updates.
